Haeckel’s intention with Kunstformen der Natur was to introduce the hidden features of the organic world. He developed into a little known realm of fascinating form and beauty. The plates of radiolarians, foraminifers, sponges, medusae, peridiniams, diatoms, ciliates or flagellates are magnificent works of art and served as pattern for the arts and crafts of the L’Art Nouveau epoch.
